GEORGE WILSON DUDLEY AND ARTHUR LOUIS DUDLEY, OF STAUNTON, VIRGINIA,ASSIGNORS TO lTHE NUMEROGRAPH MANUFACTURING COMPANY, OF CHARLESTON, WESTVIRGINIA.

WEST VIRGINIA, A CORPORATION OF RECORDING AND ADDING MACHINE.

SIPECIFICA'JIION` forming part of Letters Patent No. 756,340, datedApril 5, 1904. Application filed September 24, 1901. Serial No. '76,321iA (No model.)

T0 all whom, it may concern:

Beit known that we, GEORGE IVILsoN DUD- LEY and ARTHUR Louis DUDLEY,citizens of the United States, residing at Staunton, Augusta county,Virginia, have invented certain new and useful Improvements in Recordingand Adding Machines, of which the following is a specification.

Our invention is an improvement upon the recording and adding machinedescribed in application for Letters Patent of the United States, filedby us March 28, 1900, Serial No.` 10,105, the present improvementsrelating to the paper-carriage mechanism,means whereby the saidmechanism may be thrown outof operation, means for resetting theadding-disks to zero, means for locking the keys during the resettingoperation in order to prevent disarrangement of the trains ofmechanisms, means for controlling the detents of the carryingtrains, acorrecting mechanism, and other features hereinafter described, andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a rear view of our machine.Fig. 2 is a vertical sectional view of the paper-carriage with adjacentmechanism with parts in elevation. Fig. 3 is a plan view of the machine.Fig. `4 is a central vertical section of parts relating to the addingmechanism. Figs. 5 and 6 arel views of details. paper-receptacle.

In the present specification we have confined ourselves mostly to themechanism which is new in respect to that shown in the applicationreferred to above, it being thought unnecessary Fig. 7 is adetail viewof the to repeat the description contained in said ap plication. It willbe understood that the printing-disks a and adding-disks b are operatedby selectors 99SL and 99X, respectively, which are in turn set up by theoperation of the keys and by connections extending from anoperating-handle 19, all of said operations and Aconnections being fullydescribed in the application referred to. Further, the adding mechanismis provided with means for carrying digits from order to order, theCarr-yingwheels being indicated in the present case at 96', thismechanism also being substantially the same as that described in saidapplication, excepting as hereinafter noted.

The paper-carriage comprises end frames 1, connected by a plate 2, whichhas connected thereto the pivot-bar 3, adaptedto both turn and slide ina track or way L of tubular form, which is slotted on its upper side forthe passage of the web 5, connecting the said pivotbarY with the saidlplate 2. The track or way is rigidly supported by the fixed standards 6,extending up from the base-frame 7. The end framesof the carriage arealso connected by a bar 8, which passes loosely through operating-bars9, extending downwardly and -having hooks 11 engaged by a cross-bar 10of a pair of levers 12, which are pivoted on a bar 13, rigidly supportedin the standard 14C and one of the standards 6, Fig. 1. The levers 12are connected by a cross-rod 15, so that they, with the cross-rod, movetogether as one frame.`

The forward ends of the levers 12 are arranged to be operated by therollers 16, (dotted lines, Fig. 2,) carried by arms 17, fixed to theshaft 18, which is turned backward and forward as the main hand-lever 19(dotted lines, Fig. 2) of the machine is swung forward and being throughthe master-wheel 20, on the shaft of which the hand-lever is fixed, and

through the gear-wheel 21, fixed on the said shaft 18, these parts beingsimilar to'those in v our previous application referred to above.

As the main hand-lever is swung forward to set up the number to theprinting-point and after the printing-disks are set up the continuedforward movement of the hand-lever will through the connections justdescribed cause the depression of the'levers 12, and the cross-bar 10will draw down the hooked rods 9, and thus cause the carriage-frame tobe tilted forwardly to force the paper lagainst the type, and thus makethe impression, it

being understood that the paper passes between the paper-feed roller 22and the roller 23, carried by the carriage-frame, thence up in front ofthe platen 24, also carried by the carriage-frame, and then up betweenthe crossrod 25 of this carriage-frame and the cuttingbar 26.

NVhen the main hand-lever is swung rearwardly to restore theprinting-disks and other parts, as described in our said formerapplication, the reverse action takes place, the arms 17 moving so as tocarry the rollers 16 away from the levers 12, and thus allowing saidlevers to rise and the paper-carriage to swing back to normal position,this action taking place in the first part of the return movement of themain hand-lever 19 to the position shown in Fig'. 2. Springs 29, one endof each of which is connected to the rod 9 and the other end to thefixed framework at 30, serve to swing' the paper-carriage and the levers12 to their normal position after the rollers'l free the said levers 13.

r1`he paper-feed roll 22 is carried by arms 27, Fig's. 1 and 2,pivotally supported on a shaft 28, journaled in the end frames 1 of thepaper-carriage frame. These arms at their lower ends have pins 31extending into notches or slots in arms or collars 32, fixed on a shaft33, which is journaled in the end frames of the paper-carriage. rllisshaft is nuclei' tension of spring's 34, tending' to press thepaper-feed roller against the roller 23 to secure proper contact andpressure for feeding the paper. A linger-lever 35 on the end of theshaft when pressed down serves to force the feed-roll away from theroller 23 for the proper manipulation of the paper in placing it,removing', or adjusting it, and when the finger-lever isrreleased thesprings will return the feed-roll to normal position. The feed-roll maybe turned by hand through the knob or finger-piece 36.

To turn the feed-roll automatically, it is provided with gear-wheels 37,Fig's. 1 and 2, one at each end, meshing with gears 38, fixed on theshaft 28,. This shaft is connected by a spline with a sleeve 39,carrying a ratchetwheel 40, which is adapted to be turned one tooth ateach forward movement of the lmain hand-lever 19 through a pawl 41,which is4 pivoted to aglever 42, pivoted on the crossrod 13, the forwardend of said lever being operated by a cam 43, fixed on the shaft 18,before mentioned, said shaft having its bear ings in any suitable partof the framework. The lever 42 is returned to its upper normal positionby a spring 44, one end of which is fixed to the rigid cross-bar 13 andthe other end being' secured tothe lever. By this spring raising thepawl-lever the pawl is retracted for anew tooth when the hand-lever isswung rearwardly. The pawl is also pressed by a coil-spring 45 to`remain in contact with the teeth of the ratchet.

To throw the pawl out of action so that the paper-feed roll may beturned in either direction by hand, we have provided a release-lim ger46, carried by a shaft 47, journaled in the standards 6 and operated bya finger-lever 48. The, release-finger when moved strikes' the pawl andthrows it out of the ratchet-teeth against the tension of the spring'.45, allowing the feed-roll to be turned in either direction.

Ve have provided means whereby the paper-carriage may be thrown out ofoperation so that the adding' portion of the machine may be used withoutcausing' any impression to be made by the yprinting mechanism. For thispurpose the hook-bars 9 are thrown out of normal position, so as not tobe depressed by the operation of the levers 12, which levers in thepresent machine are operated at each action of the hand-lever. To tln'owthe hooked arms out, they are provided with cam-shaped slots 49, Fig. 2,through which passes a crossbar 50, carried by arms 51, pinned to arockshaft 52, journaled in the standards 6. The shaft has a finger-lever52l fixed thereto, and by moving' this the arms 51 will be swung tocause the cross-bar 5() to throw the hooked arms 9 forwardly, so thattheirhooks will be disengag'ed from the cross-bar 10, and so long as theparts are held in this position the Inachine may be operated withoutcausing the paper-carriage frame to be swung to make the impression, theadding mechanism alone bcing effective. The arms 51, with the cross-bar50, may be used also to turn the paper-feed roll step by Step by hand,for which purpose the said bar 50, which may turn in its bearings in thearms 51, is provided with an enlargement or roller 53, bearing on theupper edge of the pawl-carrying lever 42. A second finger'lever 54 isfixed to the shaft 52 to turn the same in the opposite direction fromthat of the releasing-lever 52, before mentioned, and through this leverand connections described the pawl-carrying lever may be depressed toturn the ratchet-wheel one step, and this action may be repeated to getthe desired number of step-bystep actions of the paper-feed roll. rlheslots 49 of thehooked arms are extended at 49 to permit the crossbar 50to move in the action just described without affecting' said hookedarms.

The shaft 52 is under sprmg tension either way it is turned, saidtension restoring' the shaft to normal position whichever way it isturned, said spring tension being lsecured by a spring 55, Fig. 5,within a case 56X, Fig. l, rigidly fixed to one of the standards 6, saidspring' having' both of its ends projecting to be engag'ed by shoulderson a block 57, secured to the shaft 52. Thichever way the shaft isturned one of the shoulders on said block will engage one of the ends ofthe spring and will be returned thereby.

1t will be understood that the paper-carriage besides having itsswinging' movement IOO is adapted to be moved longitudinally intodifferent positions in relation to the printingdisks, the position ofwhich is indicated in dotted lines in Fig. 1 at a. In this longitudinalmovement the pivot-bar 3 simply slides in the track or way 4,A itfitting snugly therein. This adjustment is to permit columns of figuresto be printed side by side on the sheet.

In order to hold the carriage in any of the several positions to whichit may be adjusted, we have provided a pawl 56, extending up through aslot in the fixed track to engage any one of a series of notches 57 inthe pivotbar, as shown in Fig. 1. The pawl is carried by a shaft 58,kjournaled in one of the standards 6 and the support 59, and it has afingerlever 60, which when pressed will throw the pawl out of engagementwith the pivot-bar, so that the paper-carriage can be shiftedlongitudinally. A spring 61 will return the shaft and pawl when a notchcomes opposite the pawl.

Resezfz'ng @deling-flasks to ewa-In order to reset the adding-disks b toZero,wehave provided means whereby the carrying-pawls 61, which act incarrying digits from one order to the next higher, may be thrown out ofconnection with the carrying-train, this means consisting of a shaft 62,Fig. 4, journaled in the frame of the adding mechanism and having a wing63, Figs. 3 and 4, adapted to engage the walls of slots 64, formed inthe pawls, through which slots the shaft extends. The shaft has afinger-lever 65, and when this is pressed the wing will move all of thecarryingpawls out ofconnection, and the adding-disks may then be resetby turning the knob 66 on the shaft of the adding-disks. This shaft maybe provided with any suitable pins or devices adapted to engage parts onthe adding-disks to return the same to Zero position, such means beingshown in the application referred to. necessary to withdraw the detents67,. Figs. 3 and 4, from connection with the gear-train, and for thispurpose we make a connection between the wing-shaft 62 and the master-Wheel 20, so that when the carrying-pawls 61 are thrown out of 'actionthe same operation will throw out the detent 67, and thus free theadding-disks for the resetting action, the said detent being arranged inthe same relation to the adding and printing trains as is shown in myapplication mentioned and operated from the master-wheel in a similarmanner to that shown in said application. This connection to themaster-wheel consists of an arm 68 on the shaft 62, a link 69 connectingsaid arm with an arm 7 O on a shaft 71, journaled in the framework, saidshaft having also an arm 72 connected by a link 73 with a lever 74,pivoted on the shaft of the master- Wheel and arranged so that whenoperated it will contact with apin 75 on the master-wheel In order tofree the adding-disks, it isy and turn the same, and this master -wheelthrough its connection with the detent 67 will throw the same out ofoperation to free the adding-disks for the resetting action to Zero. Theconnection mentioned consists of the gear 68X, Fig. 3, the cam 83X, arm81X, and the shaft X, Fig. 3, carrying the detents,.similar numeralswithout the exponent- "m being used to designate like parts in theapplication mentioned.

Key-'locking merma-7e have provided means whereby the key mechanism islocked when the adding-disks are to be reset to Zero and the detents arewithdrawn, so as to free the adding-disk trains. The object of this isto prevent the operation of the machine while the detents are thrown outof connection, and thus present disarrangement of the parts at thistime. In order to effect this locking action, we provide themaster-wheel with a cam 76 and a lever 77, pivoted to the base of themachine, which lever has its end in the path of this cam, while itsopposite end engages a slide 78, guided in the framework, said slidehaving a series of notches 7 8 to normally receive the key-levers whenthey are depressed and having plain unnotched portions to form stopsIforthe key-levers when the slide is shifted into locking position, whichaction takes place simultaneously with the release of the carrying-pawlsand with the throwing out of connection of the detent. The varioustrains of wheels being free at this time, any intentional or accidentaloperation of the keys would throw the connections out of order; but thelocking mechanism for the keys acting simultaneously with the releaseofthe adding-disks will effectually prevent any disarrangement of theconnections at this time, and it will be necessary to restore thedetentsand pawls to engaging position before the lock-baris withdrawn to unlockthe keys. In other words, the lever 19 must be returned fully to itsnormal rearward position to unlock the keys, and when in this positionthe detent 67 is in engagement, as are also' the carrying-pawls 61.

In order to allow the adding-disks to move freely in the setting-upoperations and at the same timeto prevent overthrow of the addingdisksin the operation of carrying or resetting, a special arrangement ofdetent mechanism for the adding-disktrains is provided.

The spring-detents 79, Figs. l and 4, are fixed to a rock shaft or bar80, journaled in the side frames 81 of the adding mechanism, there beingone detent for each carrying-gear wheel. An arm 89, connected with thesaid shaft, is in turn connected by a link 83 with a bell-crank lever84, pivoted to one of the side frames 81, and having a pin 85 arrangedto be acted on by a cam-disk 86, which is connected with the pin-drum87, these parts being loose on the shaft 18, before mentioned, and

IOO

adapted to be operated for the carrying operation each time thehand-lever 19 is moved rearwardly by a pawl 88, carried by a disk 89,fixed on the said shaft 18. The cam has notches or low parts 89 thereinadapted to receive the pin 85 during the setting-up action, the saidcamdisk remaining at rest during this time,the disk 89 alone turning andthe pawl 88 moving around to engagea new pin 90 for a new action. Thenthe pin 85 is in the notch, the detents 79 are free and rest butslightly on the toothed wheels of the carrying-train. When, however, thecam-disk is turned by the pawl 88 the pin 85, riding' upon the peripheryor high part of the cam, will press the detents into strong contact withthe said toothed wheels, and as at this time the carrying is being donethere will be no danger of overthrow of the carrying-disks. The detentsare also thrown into operation when the knob 66 of the adding-disks isturned to reset the adding-disks to zero, for which purpose the arm 82is extended and has a hooked end 93, acted on by a cam or collar 91,said collar having notches or low parts 92 to normally receive thehooked end 93 of the arm 82; but when the knob is turned to reset thedisks the periphery of the cam, acting on the hooked end of the arm,will throw the detents into strong contact with the toothed wheels ofthe carrying mechanism and prevent the same from becoming disarranged,it being understood, as before stated, that when this resetting actiontakes place the carrying-pawls and the detents 67 have been thrown outof connection, and the adding-disks, with their gear-trains, are freeand are liable to become disordered were some means not provided toprevent this.

@vreet/ng Zamba-A correcting device is provided by which any of theadding-disks may be individually set or adjusted to correct any errors.This consists of a sleeve 94C, arranged to slide upon a cross-rod 95,(dotted lines, Fig'. 1,) which is supported in the frames 81 of theadding' mechanism. This sleeve carries a toothed wheel 96, adapted tomesh with any of the toothed wheels of the carrying mechanisms, forwhich purpose the sleeve may be slid longitudinally by means of afingerpiece or button 97. The sleeve is provided with a scale marked tocorrespond to the different orders of the adding-disks and by making thenumber of the desired order register with a certain part of the frame,as at a', Fig. 3, which will perform the function of an index orpointer, the toothed wheel 96 will then be in mesh with the toothedcarrying-wheel 96 of the order desired, and by then throwing thecarrying-pawl 61 out of connection the toothed carrying-wheel and itsdisk may be adjusted as desired to correct any errors.

ln order to indicate the last order of digits which has been operated oradded, we provide a pointer 98, Fig. 3, carried by the standard reame99, which shifts with the group of adding-selectors 99. This pointermoves over an indicating-plate c, having a scale composed of numberscorresponding to the di'erent order of digits, the said plate having anopening through which the figures are exposed to View. By means of thispointer it can be ascertained at a glance which of the several ordershave been operated or added last, and by means of the corrector-wheelthe operator may connect with and adjust the proper toothedcarryingwheel to set the corresponding adding-disk as desired.

The sleeve carrying the ratchet-wheel of the paper-feed is held againstlongitudinal displacement by brackets CZ, which are secured to thestandards 100, supporting the printingdisks. These brackets are slottedor forked (dotted lines, Fig. 2) to permit the swinging of thepaper-carriage. The brackets have forked extensions 101, which sustainthe arms or rods 9 laterally. These arms, together with the attendantmechanism, have no lateral movement, but remain fixed in relation to thelongitudinal adjustment of the wiper-carriage.

Proper-'recapmele.The paper-receptacle is in the form of acylindercomposed of two semicylindrical sections 102 103, supported upon an arm104 of the paper-carriage. The section 102 is adapted to be turnedwithin the section 103, so that the paper may be rolled up and placed inposition, after which the said section is turned into the position shownin Fig. 2 to make the parts assume cylindrical form, and the end of thepaper is then withdrawn through the slot 105 left between the sectionsand passed through the feed-roller. The movable section is held in openposition by means of a latch 106.

R/bb0n-fced.r `he ribbon-spools 106 have their shafts supported instandards 107 and are slightly offset in relation to the axis of theprinting-disks. The shaft 108 of each ribbon-spool is provided with aratchet-wheel 109 to be engaged by pawls 110, carried pivotally bybell-crank levers 111, which are pivoted to any suitable part of theframework, said levers being arranged to be operated by the arms 17,before mentioned, said arms engaging pins 112 on the bell-crank levers.The pawl-levers 110 are pressed toward the ratchetwheels normally bysprings 113, carried by the bell-crank levers 111. The pawl-levers havealso arms 11a, provided with pins 115, arranged to operate the detents116 of the ribbon-ratchets 109, so that when either pawl is thrown outthe detent corresponding to its ratchet will be thrown out also. Thearrangement is such that when one pawl is out the other is in engagementwith its ratchet, as shown in Fig. 2, and for this purpose the pawls arearranged to be acted upon by cam-blocks 117 118, reversely set inrelation to each other upon a shaft 119. By turning this shaft one IOCIIS

of the cams will engage its pawl to throw it out of operation, and atthe same time the other cam-block will free its pawl, so that this underthe tension of its spring 11B-will engage its ratchet-wheel. l
